A method for enabling a printing machine having a customer billing interface to bill the customer for different types of printing operations performed includes programming variable rates for printing operations into the printing machine. With receipt of a machine enable signal from the customer billing interface, the printing operation is initiated. The printing machine determines the type of printing operation performed and sends the corresponding billing signal to the customer interface.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of enabling a self-service printing machine having an external customer interface device to bill for printing jobs which may require a printing machine to perform various types of printing operations comprising the steps of: programming different billing rates in the printing machine with the billing rates being a function of the printing operation; receiving an enable signal from the external customer interface device, indicating customer credits therein; controlling the printing of sheets fed to the printing machine, comprising: feeding a sheet to the printing machine; printing information on said sheet or leaving said sheet blank; determining if said sheet is blank, printed on one side, or printed on two sides to identify a type of printing operation; sending a signal to the external customer interface device corresponding to the billing rate amount programmed for said identified printing operation performed on said sheet; deducting said billing rate amount from said customer credits contained within the external customer interface device; determining whether customer credits remain in the external customer interface device after deducting said billing rate amount from said customer credits; disabling the printing machine if no customer credits remain within the external customer interface device; and sending an enable signal, after each said sheet is printed, from the external customer interface device to the printing machine if credits remain within the external customer interface device; and repeating said controlling step until printing is terminated.
2. The method according to claim 1 , wherein said external customer interface device comprises a coin box.
3. The method according to claim 1 , wherein said external customer interface device comprises a card reader.
4. The method according to claim 1 , wherein said external customer interface device comprises a bill changer.
5. The method according to claim 1 , wherein said external customer interface device comprises a token box.
